To all whom it may cxmcem.l I

p Be it known that I, JOSEPH E. DE Brssonor,

`features diagrammatic,V the parts being ,inf

the position for loWWater level indicating.

Fig. 2 is asimilar view of some of the parts shown' in Figi inthe position for yhigh f water level indicating. Fig' 1s a similar 13 of the said chamber v iew with the said parts in intermediate-pos1t1on. Figa 1s a. view part sectional and part inY elevatioubfja modification of the gh level limiting ring. 1- Fig. 5 is a similar my alarml with the range of action limited to the ordinary` range plied to a water tank.

by piping with a boiler B, the water level kin which it is desired to regulate, the upper connection 10 being connected above the de s'ired water levell `and-the'l-lmver connection In the upper part of- 11 below said level. the said chamber A, and approximately eentral thereof and approximately at the higher water level is provided a horizontally` disosed supporting ring C shownl as supported by lateral supports 12. At a point-approximately at the lower water level the said chamber Ais provided with a; laterally disposed arm D constituting a lateral extension A in which is housed a lever arm 16, generally horizontally disposed within the said chamber. lever arm 16 is extended outside thesaid chamber A. by means of a horizontal .shaft 14 at its outer end and which extends at right angle-s to a st-ung box intheside of the said exten lsion vD and-is providedA on the outside ythe automatic startif vlew of another modification of the same.. Fig.` 6 is a View similar to that of Fig. 1 of for a boiler. Fig. 7 is a view' similar to Fig. 1 of my alarm ap-lv led to reciprocate in the The Suid s the said arm 16 and through with an upwardly extending branch arm 15, which'flatter is utilized as an electrical con`- tact arm. The laterally disposed lever arm 16 and vertically disposed lever arm 15 are united by the horizontal shaft 14 and pivctally supported therein?, and unite to oon'ipose a rocker arm lil. 'lhe inner end of "thesaid laterally disposed lever arm 16 is provided with a lower lient ball F of 1nodcrate floating capacity., und which is adapted to rise and lower with changes in water level and therebymove the said rocker arm E so as to make electrical contact in accordance with prf-xdeteiniinedA adjustment, to in-f dicate high or low Water level. As shown contact will be made by the contact arm 15 vwith the mating contact Gr at the condition of low Water, and at .lil for high water. The utilization ot such contacts for producing an alarm may be eilected by ordinary meth- `ods,fas, for instance, by means of a battery and bell or gong. The said -contacts may also be utilized by Well known' methods. for and stopping of purpose of autopuinping devices vrfor the y matic'maintenance of Water level. The location oi theysaid lower float ball F is rgenerally ring C. l l

A: thrust rod J is pivoted by its lower end 17 to the upper side of the said lower oat ball F and extends generally vertically and upward 'therefrom through the said supporting ring C and through an axialpassage Way 18 in upper iloat ball I and is adaptsaid passage way with the rise and fall of the said lower float ball F relatively to thel said upperiioat ball I. The' upper end of the seid thrust rod J is guided by the said passage way 18 when the said upper float ball I is resting on and supported by the said .supporting ring C during conditions of normal or low water level and serves to guide `the said upper float ball I with reference to the said su porting ring C when the said upper float ball I is floating above the inal conditions of high Water level. Stop K adjustably mounted on thesaid thrust rod J as by meer It a set screw i9 engages with the under s le ci: the said upper float ball l and limits the lower float ball F and upper float ball I.

In Fig. Il .is shown a supporting ring Cl held in place by'means of curved elbow connections 052 which; are connected bv bolts 2O directly below the said Supporting closeness lof the saidv said ring ,C durin nor-v los - ring C, and the contactarm Asupport comprising a 4single central vertical rod L adjustably su ported in the head 21" and connected at its ower end by a ball and socket swivel joint M with a set of curved elbow connections 22,

In the tank N the supporting ring C3 is supported y a bracket 23 to the side wall 24 of the tank.

The fixed electrical contacts G and H may bemade adjustable by ordinary methods.

In operation, under normal conditions of water level the said lower lioat ball willv be submerged and tend to rise and will b'e limited in such tendency b the said stop K in contact with thelower side of the said upper float b'all I and the weight of the said upper floatball, whiclrrests on .the said supporting l5 is intermediate the said fixed contact points G and H. As the water level rises due to iniow of a supply of water a condition of level Ais reached at which the 'said upper float ball I is lifted from the supporting ring C, permitting the lower float Fto rise by its buoyanej7 until the contact arm' l5 makes contact with the fixed high water contact H.

As the Awater level lowers, theupper ball I is'seated on the ring C and as the level continues to fall a point is reached at which the lower ball F is no longer submerged and responds to a urtherfall in'. the level so as to bring the movable contact arm l5 'nally into contact with the fixed contact G corresponding to the predetermined pointV of low' water level. i

I clalm as my invention: 1. In a water level regulator,r a contact arm pivotally'mounted and provided with a float ball, the said -float ball free to respond to low water conditions, restraining means operative to limit 'the movement of said ball during normal conditions of water level, and the said restraining means being released and inoperative during high water conditions, the said restraining means com-l prising a second float ball that is operative during'such high water conditions. l

In a water level regulator, a contact arm pivotally mounted and provided with a lower float ball, the said ball free to respond to low water conditions and a higher float ball having a ring support, a thrust rod attached to said lower ball and extending upwardly therefrom through said upper ball, the said upper ball resting on said ring during `normal and low water conditions, a stop on said .rod in contact with said upper ball during normal water conditions .and restraining said lower ball during such conditions. l

3. In a water level regulator,a lower .tloat ball and an upper float ball, a thrust rod attached to said lower lioat ball and extending upwardlythrough said upper ball,

a stop on said rod, a'ring support for said upper ball, the said upper ball resting on said ring during normal and lowwater conditions, the said lower ball vfree to fall in response to low water conditions, restrained from rising during normal water conditions n .by said stopl 1n contact with said upper ball,

and the said vupper ball free torise during high water conditions and permit a rise of said. lower ball during such conditions.

4. In a water level regulator, a contact arm pivotally mounted and provided with a lateral extension, a lower float ball secured vto the said extension and generally -free to respond to low Water conditions, a thrust rod secured to the upper side of the said lower ioatand extending upwardly therefrom, a stop on said rod, an upper float ball, an axial passageway through 'said ball, fitting said rod, and permitting `freely reciproca-ting motion of the same, a supporting ring surrounding the said rod and adapte to receive the said upper fioat ball and sup port the same during normal and low water conditions, and the said stop incontact with the said upper float balll and adapted thereby to limit the rise of said lower' float ball during such condition. n,

5. In a water regulator, in combination,

a lower float ball and an upper Hoat ball,

an opening through the said upper floatball,

a rod extending upwardly from the said f lower ball, through said'opening in the said upper float ball and fittin the same a stop on the said rod, means o support or sind upper float ball operative during normal and -low water conditions, the -said lower float ball free to fall res 'onsive to low water conditions, and limite in its lupward' movement during vnormal conditions by the said stop in contact with the said upper float ball.
